The K4020 is a microprocessor circuit design, high accuracy, digital readout, light duty STROBOSCOPE and TACHOMETER that is ideal for inspecting and measuring the speed of moving gears, fans, centrifuges, pumps, motors and other equipment used in general industrial maintenance, production, quality control, laboratories and as well as for school and colleges for demostrating strobe action.

Features:

• Simply aim and synchronize the strobe's flash rate (fpm) with the speed (rpm) of the object
• Direct reading in RPM
